feat: add CI/CD workflows, fix module path, add missing cmd/ entry point

- Add GitHub Actions CI workflow (test + build on push/PR)
- Add GitHub Actions Release workflow (auto-build on tag push)
- Fix go.mod module path: lume -> github.com/Tyooughtul/lume
- Update all import paths to match new module path
- Fix .gitignore: /lume instead of lume (was ignoring cmd/lume/)
- Add cmd/lume/ entry point (was missing from repo)
- Fix history_test.go: add missing argument to RecordSnapshot
